I have a 40 year old shed that was converted to a cottage with no permits or anything to code. I'm remodeling and repairing damage and have come across carpenter ant damage in a section of a structural beam on the bottom exterior wall. Short of taking the whole cottage apart piece by piece and rebuilding, any ideas of how to reinforce this beam? I have yet to take the siding off the the other three sides to see if there is any other damage. There is also no foundation and the beams are supported by shanty piers made of rock and wood. Sorry, I couldn't upload a photo, but it is basically a picture of a 6 x6 sill beam with carpenter ant damage (about 30%) with studs nailed directly to it instead of a sole plate.
